Function/Subroutine Documentation

integer function icmax1 (integer n, complex, dimension(*) cx, integer incx)

ICMAX1 finds the index of the first vector element of maximum absolute value.

Purpose:

!>
!> ICMAX1 finds the index of the first vector element of maximum absolute value.
!>
!> Based on ICAMAX from Level 1 BLAS.
!> The change is to use the 'genuine' absolute value.
!>

Parameters

N

!>          N is INTEGER
!>          The number of elements in the vector CX.
!>

CX

!>          CX is COMPLEX array, dimension (N)
!>          The vector CX. The ICMAX1 function returns the index of its first
!>          element of maximum absolute value.
!>

INCX

!>          INCX is INTEGER
!>          The spacing between successive values of CX.  INCX >= 1.
